Afternoon everyone,
I just got a 1975 CB 750 and I’m cleaning the Keihin carbs and after cleaning them I noticed that when I install the slider with Needle valve it will not seat into the carb body all the way. It stops before it bottoms out like the other carbs. It is possible that the needle jet in the body is damaged and will not allow the needle valve to extend all the way, but I can’t see any damage. Attached are a few pictures to help explain what my issue is.
Any help would be greatly appreciated
First picture is the #2 carb that seats properly
This picture is from the problem carb (#1) if I apply pressure to close the gap further, the slide gets stuck.
